5 FAQs of Al2o3 high temperature alumina melting ceramic crucible

Frequently Asked Questions About Al₂O₃ High-Temperature Alumina Melting Ceramic Crucibles

What is this crucible made of?

This crucible is made from high-purity aluminum oxide (Al₂O₃). It contains over 99% alumina. This material gives the crucible strong resistance to heat and chemicals.

How hot can it get before it fails?

It can safely handle temperatures up to 1700°C (3092°F). At this heat level, the crucible stays stable and does not melt or crack under normal use. Always avoid sudden temperature changes, as they may cause damage.

Can I use it with any metal or chemical?

It works well with most metals like gold, silver, copper, and platinum. It also resists many acids and alkalis. However, do not use it with hydrofluoric acid, strong alkalis at high heat, or reactive metals like aluminum or magnesium—they can attack the alumina surface.

Why choose alumina over other ceramic crucibles?

Alumina crucibles offer better thermal stability and longer life than many alternatives. They do not react easily with molten materials. Their smooth interior reduces contamination. These features make them ideal for lab work and small-scale melting tasks.

How should I handle and store it?

Always handle the crucible with clean tongs. Avoid dropping it or hitting it against hard surfaces—it is strong but still brittle. Store it in a dry place away from dust and moisture. Before first use, heat it slowly to remove any trapped moisture and prevent cracking.
